Paleoceanography is the study of Earth's ocean history, reconstructing past temperature, chemistry, circulation, and biology from sediment cores, fossil shells, and geochemical proxies. By reading the chemical fingerprints locked inside foraminifera shells and ancient marine sediments, scientists can reconstruct millions of years of climate change with remarkable precision.
These simulations let you explore the key tools and events of paleoceanography — from oxygen isotope thermometry and sea-level reconstructions to thermohaline conveyor shutdowns, carbonate dissolution depths, and the dramatic ocean anoxic events that deposited black shales across ancient seafloors.
